You drop for the ball without holding back
The compression goes with the joint through deep flexion, which is exactly the movement you repeat at the kitchen line. When you stop anticipating the discomfort, you get there sooner.

Seamless compression knee support, with two side stays and a silicone ring around the kneecap, designed for the move you repeat most at the kitchen line: going down and coming back up.
The stays bend with you on the way down and spring back on the way up, so your knee does not drift inward. The silicone ring wraps around the kneecap and keeps it centered.
With no inner seam there is no chafing behind the knee, which is why it does not roll down even if you bend a hundred times.
Available individually or as a 2-pack with savings.
Material: stretch knit fabric, seamless construction, with a silicone ring around the kneecap and two side stays.
Sizes: M, L and XL.
Colors: gray, blue, red and black.
Contents: 1 knee support per unit (not a pair).
It is unisex and stretchy. If you're between two sizes, write to us with your thigh circumference and we'll tell you which to order.
Pull it up from your foot with your leg straight, until the kneecap is centered in the widest part. Then bend a couple of times so it settles.
It should press evenly. If it leaves a deep groove at the top or your calf feels swollen afterwards, the size is too small.
By hand, with cold water and mild soap, after every two or three uses. Dry it in the shade, laid flat.
No hot machine wash, no dryer and no fabric softener: softener destroys the elasticity and the knee support stops holding.
Tracked shipping. Estimated delivery of 6 to 9 business days from when you confirm your order.
EU and UK customers have 14 days from receipt to return it if it doesn't fit. Products also carry a 3-year legal guarantee under Spanish law.
The knee support is 28 cm (11 in) long in all three sizes. What changes is the circumference. Measure above and below the knee, standing with your leg relaxed.
| Size | Circumference above the knee | Circumference below the knee |
|---|---|---|
| M | 34-42 cm (13.4-16.5 in) | 27-34 cm (10.6-13.4 in) |
| L | 39-48 cm (15.4-18.9 in) | 30-38 cm (11.8-15.0 in) |
| XL | 40-50 cm (15.7-19.7 in) | 32-42 cm (12.6-16.5 in) |
Manufacturer's measurements. If you're right between two sizes, take the smaller one for more compression and the larger one for more comfort. And if in doubt, write to us with your measurements at info@pasionpickleball.com and we'll tell you which to order the same business day.
The problem
The point is played at the kitchen line, in a low position, and from there you push out, stop and drop again. A match of an hour and a half is hundreds of deep bends with the leg loaded.

Dropping for the short ball is no longer the problem. The problem is getting back up, and each time it takes a bit longer.
You go down sideways, holding the rail, the day after playing. And you tell yourself it's age.
At the kitchen line you're half crouched all the time. Hundreds of bends per match that nobody counts.
Without noticing you stay upright to avoid bending. And that's where you lose half the low balls.
The day you stop dropping for short balls, your game changes. And you don't choose that day.
The change
It is not an orthopedic knee brace and it won't immobilize anything. It's compression that goes with the knee while you play.
The compression goes with the joint through deep flexion, which is exactly the movement you repeat at the kitchen line. When you stop anticipating the discomfort, you get there sooner.
On the sides it has two stays that bend with you as you go down and return to place as you come up. Your knee doesn't cave inward when you push. And with no inner seam, it doesn't rub behind the knee.
Spreading the load during the match shows most at the end: in the last game you're still going for the short ball instead of watching it go past.
Everybody is different. The FLEX is compression sports gear, not a medical device or a substitute for medical treatment. If you have a diagnosed injury or persistent knee pain, talk to your physiotherapist or orthopedist.
Before and after
Drag to see the same player with the knee unsupported and supported.
With FLEX
Without support

In motion
At the kitchen line you spend the match going down and up. Here you see the knee support in both positions: extended and in full flexion.
With no inner seam there is no hinge, which is why it doesn't roll up or rub behind the knee.
Honesty
We'd rather you don't buy it than have it arrive and be of no use to you.
If you have persistent pain or a diagnosed injury, talk to your physiotherapist or orthopedist first. This is sports gear, not a treatment.
No hype
What we can show you is data you can check yourself, and the product just as it will arrive.

Before you buy
And if you still have a doubt, write to us at info@pasionpickleball.com. Real people answer.
No. That requires orthopedic gear, usually a hinged knee brace, and a professional has to prescribe it.
The FLEX is a sports compression knee support: it goes with the joint during the movement. It is not a medical device and does not treat any condition.
That's why we chose a seamless construction. Knee supports that roll up usually have an inner seam that acts as a hinge and works its way down with every bend.
If it still moves, it's almost always because the size is too large. You can exchange it (EU and UK customers: within 14 days).
Measure around the leg above the knee, standing with your leg relaxed. The size chart on the product page also has the measurement below the knee.
If your measurement falls right on the border between two sizes, take the smaller one for more compression and the larger one for more comfort.
It shouldn't: it has no inner seam, which is what usually rubs behind the knee after half an hour of bending.
What can rub is a wrinkle. When you put it on, straighten your leg and smooth it out well before you start playing.
Yes, it's designed for that. Take it off afterwards and let your skin breathe.
What shouldn't happen: your calf feeling swollen, tingling or a cold foot when you finish. If that happens, the size is too small.
Between 6 and 9 business days from when you confirm your order. We don't give an exact date: it is an estimated window.
When it leaves the warehouse you receive the tracking number by email. If anything runs late, we write to you.
EU and UK customers have 14 calendar days from receipt to return it, no questions asked.
It must come back unused and in its packaging. Trying it on at home to check the size is not using it; playing a match with it is. If it arrives defective or we send you the wrong one, we pay the return shipping. For other countries, see our returns policy.
Each unit is one knee support. If your discomfort is in one particular knee, one will do.
The 2-pack is for those who want to wear the same on both legs, or to have one dry while the other is being washed. It costs less than buying two separately.
